Hayden will miss all of this week’s mini-camp too

Cornerback D.J. Hayden, the Raiders’ first-round pick a year ago, will miss this week’s mini-camp as his he remains in a walking boot, three weeks after spraining his ankle.
It’s the second straight year that Hayden has essentially missed all of the team’s offseason program. He had follow-up surgery for scar tissue in his abdomen last summer.
Oakland coach Dennis Allen expects Hayden to be ready for training camp in five weeks, but admitted this is another setback in the cornerback’s development.
“It’s definitely a setback, there’s no question about it,” Allen said after Tuesday’s practice. “I mean, DJ’s still a young player, he needs a lot of reps, but I don’t think it’s the end all, be all. I don’t think it’s something that he can’t overcome, but he’s got to stay into it mentally.”
Cornerback Carlos Rogers was also out with a minor calf injury, so Tarell Brown and Chimdi Chekwa were the starting cornerbacks at practice on Tuesday.
Briefly: Guard Lucas Nix had knee surgery Tuesday and is the one player Allen said is questionable for the start of training camp. … Reserve linebacker Miles Burris got a lot of first-team reps, another sign that veteran Kevin Burnett’s days in silver and black are numbered. Sio Moore is the likely starter ahead of Burris on the outside, opposite rookie Khalil Mack, and Burnett doesn’t play special teams. … The Raiders’ and Cowboys’ joint training camp practices in Oxnard are scheduled for August 12 at 4:00 p.m. and August 13 at a morning time to be determined.
